Abstract

A packaging box is fabricated by bending a corrugated cardboard plate and includes a quadrangular tube-shaped body that is rectangular in cross section and a cover for closing an opening of the body. The first cover plate is connected to a first end edge of one of the pair of first circumferential surface plates on a side near the opening and closes the opening. The second cover plate is connected to a second end edge of the other of the pair of first circumferential surface plates on the side near the opening and is adhered to an outer surface of the first cover plate. The second cover plate is split into an adhesive piece that is adhered to the first cover plate and a peeling piece that has one side connected to the second end edge and is peeled off from the adhesive piece along a breaking line.

First claim

What is claimed is:

1. A packaging box, comprising:
a body having a rectangular tube shape; and
a cover for closing an opening of the body on one side thereof,
wherein
the body is composed of:
a pair of first circumferential surface plates opposed to each other; and
a pair of second circumferential surface plates opposed to each other orthogonally to the pair of first circumferential surface plates,

the cover includes:
a first cover plate that is connected to a first end edge of one of the pair of first circumferential surface plates on a side near the opening and closes the opening; and
a second cover plate that is connected to a second end edge on the opening side of the other of the pair of first circumferential surface plates and is adhered to an outer surface of the first cover plate, and

the second cover plate is split into:
an adhesive piece that is adhered to the first cover plate; and
a peeling piece that has one side connected to the second end edge and is peeled off from the adhesive piece along a breaking line,

wherein
the second cover plate has a through hole that is disposed adjacently to a center of the breaking line in an extending direction thereof and into which a finger is insertable.

2. The packaging box according to claim 1 , wherein
the first cover plate includes, in a region thereof opposed to the through hole, a push-in piece that can be separately pushed in along an incision line.

3. A packaging box, comprising:
a body having a rectangular tube shape; and
a cover for closing an opening of the body on one side thereof,
wherein
the body is composed of:
a pair of first circumferential surface plates opposed to each other; and
a pair of second circumferential surface plates opposed to each other orthogonally to the pair of first circumferential surface plates,

the cover includes:
a first cover plate that is connected to a first end edge of one of the pair of first circumferential surface plates on a side near the opening and closes the opening; and
a second cover plate that is connected to a second end edge on the opening side of the other of the pair of first circumferential surface plates and is adhered to an outer surface of the first cover plate, and

the second cover plate is split into:
an adhesive piece that is adhered to the first cover plate; and
a peeling piece that has one side connected to the second end edge and is peeled off from the adhesive piece along a breaking line,

wherein
the breaking line is formed in a V shape convex toward the second end edge.

4. A packaging box, comprising:
a body having a rectangular tube shape; and
a cover for closing an opening of the body on one side thereof,
wherein
the body is composed of:
a pair of first circumferential surface plates opposed to each other; and
a pair of second circumferential surface plates opposed to each other orthogonally to the pair of first circumferential surface plates,

the cover includes:
a first cover plate that is connected to a first end edge of one of the pair of first circumferential surface plates on a side near the opening and closes the opening; and
a second cover plate that is connected to a second end edge on the opening side of the other of the pair of first circumferential surface plates and is adhered to an outer surface of the first cover plate, and

the second cover plate is split into:
an adhesive piece that is adhered to the first cover plate; and
a peeling piece that has one side connected to the second end edge and is peeled off from the adhesive piece along a breaking line,

wherein
the breaking line is formed in a V shape convex toward the first end edge.

5. The packaging box according to claim 4 , wherein
a pair of cutting lines is formed at both ends of the second end edge, and
the breaking line includes a pair of inclined parts extending respectively from inner ends of the pair of cutting lines toward the first end edge.
